Most of the animals the investigators seized had injuries consistent with being involved in dog fighting.

The 56 dogs are now under the care of the RSPCA and include breeds traditionally used for fighting as well as a handful of puppies and breeds that fetch large amounts of money on the pet market, such as French bulldogs.

RSPCA Queensland spokesman Michael Beatty said the raid was the result of an investigation that had been going on for months.

“It’s the first major breakthrough in Australia in about 10 years,” he said.

Mr Beatty said dog fighting rings are traditionally very well guarded and extremely secretive — which makes busting them very difficult.

“They’re very secretive operations. It’s been very hard to get concrete information. It’s a lot of he said, she said and the taskforce had to do a lot of chasing up of internet chatter and chasing leads from people,” he said.

While the RSPCA and Queensland Police are happy with the investigation, Mr Beatty said they’ve barely scratched the surface.

“We’re definitely not done. If anyone has any further information we obviously want them to give us a call [on 1300 264 625],” he said.
